Percent Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ] [ Designated as safety issue: No ]
Percent change in LDL-C = (Combination treatment value - Baseline value)/Baseline value*100
The primary efficacy variable is the change in LDL-C relative to the baseline value. Change can be expressed as a percentage change. The primary variable is assessed after 6 wks of combination treatment

    Percent change in ApoB = (Combination treatment value - Baseline value)/Baseline value*100
  • Percent Change in Apolipoprotein A1 (ApoA-1) After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ] [ Designated as safety issue: No ]
    Percent change in ApoA-1 = (Combination treatment value - Baseline value)/Baseline value*100
  • Percent Change in TC/HDL-C After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ] [ Designated as safety issue: No ]
    Percent change in TC/HDL-C = (Combination treatment value - Baseline value)/Baseline value*100
  • Percent Change in LDL-C/HDL-C After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ] [ Designated as safety issue: No ]
    Percent change in LDL-C/HDL-C = (Combination treatment value - Baseline value)/Baseline value*100
  • Percent Change in Non-HDL-C/HDL-C After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ] [ Designated as safety issue: No ]
    Percent change in non-HDL-C/HDL-C = (Combination treatment value - Baseline value)/Baseline value*100
  • Percent Change in ApoB/ApoA-1 After 6 Weeks Combination Treatment [ Time Frame: Mean of Weeks 4 and 6 on combination therapy (Last observation carried forward) ] [ Designated as safety issue: No ]

12-week Open-label, Phase IIIb Comparing Efficacy and Safety of Rosuvastatin (CRESTOR™) in Combination With Ezetimibe
A 12-week Open-label, Randomised, Parallel-group, Multicentre, Phase IIIb Study to Compare the Efficacy and Safety of Rosuvastatin (CRESTOR™) in Combination With Ezetimibe and Simvastatin in Patients With Hypercholesterolaemia and CHD
